Facilitate multiple Naming statements when creating a new Person in FactoidBuilder

[GVogeler]

Gendering Maximilian: "Wie umfangreich soll das Label bei Personen sein? Wann sollen wir Namensvarianten in Klammer anführen?" => Alternative Names would usually be Naming statements.

Additionally: relationship between Factoid.label and statements could clarify this (and similar topics) in the Guidelines

There are two questions here:

1. When creating new persons in Factoid builder, the "alternative names" should be in square brackets in the LABEL (see the Schuh example).

2. If using the FactoidBuilder to add a new person, it would not make sense to be able to add more Naming statements: the reason we can add one naming statement inline is because we already have the Source — it's necessarily selected already. If a naming variation has a different source, then it should be attributed to that source as a newly-created Naming statement.

If one point in a source is a list of a person's variant names, then there might be a use-case for this; but I'm hesistant about making it easier to do this, as someone is certain to use it to attribute all name-variations to a single source.

As people are extracting data from secondary literature, the use case of alternative spellings recorded in one source is likely, but I see the risk. Probably it would be a good idea to keep current setting for inline and ask people to add explicit naming statements for this use case?
